Installing additional aircon

[ZiezLisa 0]

I'm buying a 4 room resale hdb flat. Currently they have installed a system 3 Mitsubishi starmex aircon, but they don't have an aircon in the living room. i would like to know is it possible that i could just change the compressor to a higher capacity and get a 12000 btu blower for my living room?

Any inputs is appreciated. Thank you.
